The signing of Petr Cech could be key in Arsenal winning their first Premier League title in 12 years, according to former Arsenal goalkeeper David Seaman.

The Czech keeper ended a trophy-laden 11-year association with Chelsea on Monday after finally completing a long-anticipated move to their London neighbours.

''Chelsea's loss could, and likely will, be Arsenal's gain. In my opinion this signing could genuinely be the difference between who will come first and who will come second next season,'' Seaman told BreatheSport.

Czech ended his trophy-laden 11-year association with Chelsea on Monday after finally completing a long-anticipated move to their London neighbours.

The 33-year-old found himself behind Thibaut Courtois in the pecking order at Stamford Bridge last season and seized the chance of first-team football at another Premier League title challenger.
